Evidence of an Asian beetle that kills some types of hardwood trees has been found at a second site in southwest Ohio, leading authorities to expand a quarantine.

Both places with infestations of Asian long-horned beetles are in Clermont County, east of Cincinnati. The quarantine restricts the movement of logs, firewood and other material from an area including both sites, which are about 1 1/2 miles apart.

The Cincinnati Enquirer reports the new discovery involves beetle eggs, though no adult beetles.

The insects tunnel into tree trunks and large branches and kill several types of trees, including buckeye, willow and American elm trees. They have been identified in five states, including Ohio.
